Mechanical Product Case Representation and Case Retrieval Based on Object-oriented Technique 面向对象的机械产品设计实例表示方法及检索策略研究
During the past half century the development of Natural Language Processing has involved such courses as mechanical translation, Natural Language Understanding, and Information Retrieval. Gradually it has become one of the great applications of applied linguistics. 半个世纪以来自然语言处理经历了机器翻译、自然语言理解和情报自动检索等发展过程,逐渐成为应用语言学的三大应用之一。
Second, the applications of case-based design in mechanical design field are discussed and many key techniques about case-based design are studied, including case representation, case retrieval, case adaptation and case maintenance. 其次,本文讨论了基于实例的设计在机械领域中的应用,着重研究了其中的实例表示、实例检索、实例修改和实例存储的关键技术。
This method adequately utilizes the characteristics of mechanical components, so that it has good retrieval performance. 该算法充分利用了机械零件自身的特点,有较好的检索性能。
